Multitech MT128ISA-SD User Manual

The ISDN LOG application is used to record the handshaking and data transfer

process during communication.  It can be used for debugging purposes so it is

useful to have the log running while first starting to use the ISDN system. The

Line Diagnostic is used for on-line channel testing between the ISDN switch

and subscriber site, and getting ISDN line status.  Please refer to Chapter 4 for

detailed information.

5.  You can re-configure the parameters of step 3 by executing the ISDN Configur-

er in the ISDN Group Folder.  The Configuration dialog box also displays the

I/O address and IRQ value in the message bar.

Under Windows 3.x applications, you can configure your terminal adapter device

using either COM port emulation, the standard WinISDN interface, or the CAPI

2.0 interface.
1. COM Port Emulation.  The ISDN driver provides AT command set interpreter

to emulate modems and transfer/receive data through the ISDN network.  You

must set up your application software to the appropriate COM ports (COM3 or

COM4) to communicate with the ISDN adapter.  The AT Console program

(see Figure 2-5) can redirect the AT commands and data through COM3 or

COM4 to the ISDN driver to process them.

•  If you want to set up an Internet connection through COM port emulation,

TRUMPET is a popular Internet shareware and includes the TCP/IP and PPP

protocols with Winsock interface.  Many Windows 3.1 Internet modems use

TRUMPET to connect to the Internet and to run Internet applications such as

Netscape Navigator.  TRUMPET users should modify the Network Configuration

and Script files to access the Internet through terminal adapters.  See Appendix B

for an example of a setup modification for TRUMPET.
•  When entering Windows 3.1, you must run the AT Console to enable the COM

port emulation capability.
•  Multilink PPP is not supported at the AT Console.  You may get a Multilink

PPP connection through the applications which include a TCP/IP and Multilink

PPP stack with WinISDN or CAPI interface.
